TL;DR: 4-Substituted 1-(N-sulfonyl)-1,2,3-triazoles are selectively obtained by using the Cu-catalyzed azide-alkyne cycloaddition reaction with sulfonyl azides and provides convenient access to N-Sulfonyltriazoles in good to excellent yields.

TL;DR: In this article, the second copper center facilitates the formation of the cupracycle in the rate-determining step and stabilizes the metallacycle intermediate itself, which supports the experimentally determined rate law and sheds light on the origin of high reactivity of the in situ generated copper acetylides.

TL;DR: Aiming at developing robust molecular Ru-bda (H2bda = 2,2′-bipyridine-6,6′-dicarboxylic acid) water oxidation catalysts, density functional theory studies were carried out, the robustness of catalysts against hydration was correlated with the highest occupied molecular orbital levels of a set of ligands, and the synthesis of robust Ru(bda)L2 was directed.

TL;DR: The proposal that bimolecular cycloaddition reactions take place initially between triple bonds and sulfonyl azides to give N-sulfonyl triazolyl copper intermediates was verified by a trapping experiment and the proposed mechanistic framework is in good agreement with the obtained kinetics and competition studies.

TL;DR: In this paper, a series of para-substituted aryl chlorides were studied to see the influence of electronic effects on the reaction and it was found that the experimentally observed higher reactivity of the more electron deficient aryls is due to their ability to accept back-donation from Pd0 and form reasonably strong pre-reactive complexes.
